Description

Solar balcony water heater

The utility model is the energy conversion device that solar energy utilizes model to raise, and belongs to the new energy development project.

Utilize aspect the developmental research at solar energy at present, various solar water heater layers go out not vault, and the roof is placed and upright application is set up on ground but major part all is confined to.For building resident family, except that still there was the use possibility in attic resident family, other floor was difficult to use, so most resident families buy, electric heater, gas heater.These water heaters are used the hot water problem though also can solve to have a bath, and the energy resource consumption of some is all arranged, and often cause danger because of improper use.

The purpose of this utility model is to allow all room resident families use do not spend (energy money), not dangerous solar water heater.

The utility model adopts following structure to achieve the above object.

One, condenser system; Two, the heat pipe circulatory system; Three, water tank; Four, focusing system; Five, support; Six, outer cover.

One, condenser system

Light and heat collection adopts, several measures such as board-like, curved surface, focusing.

Concentrating collector is flat, top East and West direction is arranged some strip solar panels, the solar panel reflecting surface requires to make concave Iy curved according to focusing on, solar panel is a rectangular semicircle column type, injection molded by moulding firmly, reflective surface is the 3mm flitch, the back side is radial reinforcement, the two ends home position gives and buries the recessed heart of metal, is convenient to install.

Concentrating collector, every 50cm is wide, and 8 reflectings surface are a thermal-arrest unit, and length is made 1.5M～2M as required.

The purpose that East and West direction is placed is to make daylight no matter forward what angle to the system of combining, and its reverberation all can gather to the heat absorption evaporation tube.

Concentrator bottom be insulation material, above set up the focusing screw mandrel, on the frame of thing two sides holding screw and jackscrew are arranged, in order to fixing strip solar panel.

Reflectorized material is pasted on strip solar panel surface, the requirement of curved surface radian is that light is gathered into 2cm strip light class.There is the twice semi-circle gear at the back side.

Two, the heat pipe circulatory system

Set up a flat type evaporation endothermic tube in focusing place of the overhead light of solar panel, its width is that 60mm～80mm middle cavity thickness is not less than 5mm, skin is coated with the heat absorption blacking, and downside at one end and condensation pipe link to each other, is connected at the upside of the other end and evaporates conduit.The evaporation conduit has only one, and condensation pipe is one of every unit, links to each other with corresponding condenser.

The evaporation conduit is to the water tank bifurcated, with each unit condenser of the relative uniform distribution of evaporative air, flows back to the evaporation endothermic tube after gaseous working medium is liquefied.

One group of the every unit of condenser adopts conventional cooling measure.

Three, water tank

Water tank is formed by metal welding system, and internal layer adopts conventional anti-corrosion measure, the outsourcing insulation material.To be that plastic casing is hidden play the attractive, decorative effect to outermost layer.

Establish a deflector near condenser in the water tank, impel water tank circulation and temperature even.

Water tank is divided into the water pipe that links to each other with the bathroom, on establish a water inlet pipe, by ball valve control, the ball valve handle plastic hollow kickboard that links to each other, water completely moves valve closing on the kickboard, water is shallow, kickboard gravity discharges water valve open.

Establish overflow pipe at upper limit water level, cross discharging valve and communicate with adjutage and cause the water level overfill in case ball valve is malfunctioning.

Four, focusing system

Focusing system divides the focusing of two parts () strip solar panel, the strip solar panel of each unit is provided with the focusing screw mandrel, link to each other with the semi-circle gear on the strip solar panel, the turn screw mandrel concentrates on the light class of strip solar panel at the first half or the middle part of the evaporation tube that absorbs heat.

(2) the whole focusing of concentrating collector is because seasonal variations solar incident angle degree respective change should be placed concentrating collector the corresponding adjustment of angle.

Concentrating collector is placed on the tripod of being made by the angle bar weldering, and its lower end is a sliding tray, and the upper end links to each other with leading screw, and turn leading screw handle can be regulated the angle of inclination of concentrating collector.

Five, support

Support is welded into triangular form by angle bar, hangs on the balcony outside, all uses bolting up and down.

Six, outer cover

Connect base plate cover upper strata camber translucent cover in whole heat collector outside, prevent the mobile heat radiation of air on the one hand, two aspects prevent that dust from polluting reflecting surface, guarantees Heat-collecting effect.

Concentrating collector unit reflecting surface can be injection molded fixed according to test angle one piece, can save production cost simplified structure but often because of the error on producing influences spotlight effect, solar collecting performance is corresponding inferior like this.On reducing production costs, can consider this way.

Because having adopted above-mentioned measure, the utility model to have following advantage to be suitable for balcony uses.

Stripe shape solar panel East and West direction place be again plate, do not pick up retaining mutually, can accept sunlight all day, need not tracking system, alleviated weight.

2. the used metal object in each unit is few, has only a heat absorption evaporation tube.

3. the heat absorption evaporation tube is flat type, and East and West direction is placed and absorbed photo-thermal, in flat type pipeline liquid refrigerant and gaseous working medium is taken their own roads, and does not disturb mutually, has increased daylighting area simultaneously, and high optically focused impels generation high temperature, quickens circulation, increases heat exchange efficiency.

4. adopt hot pipe technique that concentrating collector is separated with water tank, can be placed on the balcony eminence to water tank, the weight of water tank and water is placed on the building wall, alleviated the balcony load, water tank has arrived eminence, can utilize self pressure current of water to go into the bathroom and use.

5. the curved surface focusing system of strip solar panel has improved the optically focused ratio, makes burnt class be in the optimum position all the time, quickens thermal cycle and has improved Heat-collecting effect.
